Bharti Airtel, one of India’s leading telecommunications service providers, announced a pioneering initiative to provide metro commuters with uninterrupted connectivity by deploying high-capacity nodes 35 metres below the Hooghly River.
Airtel has made infrastructure investments in preparation for the service’s commercial launch, which is anticipated soon. This makes Airtel the first operator to offer seamless connectivity across the 4.8-kilometer stretch of Kolkata‘s East-West Metro corridor that connects Howrah Maidan to the Esplanade.
Airtel has connected the 4.8-kilometer stretch between Howrah Maidan, Howrah Station, Mahakaran, and Esplanade stations via fibre to enable this transformative service.
Meanwhile, the high-capacity nodes have been installed at each of these stations to provide seamless connectivity, allowing commuters to enjoy blazing 5G speeds, uninterrupted voice calls, and data transmission, all of which improve the daily commute experience and allow customers to stay connected and productive while travelling.
“Airtel is committed to pushing boundaries to better serve its customers. This initiative to provide under-river tunnel connectivity will certainly make a difference to commuters where they will get to access to High-Definition video streaming, gaming, multiple chatting, instant uploading of photos and more, along with enjoying the scenic stretch below river Ganga,” Ayan Sarkar, CEO – Bharti Airtel West Bengal and Odisha, said as per a press release.
The first underwater metro in India, which connects Howrah and Kolkata, is a feat of engineering that will soon be open to the general public. It is set to start operations in June 2024.
India’s First Underwater Metro: All You Need To Know
Kolkata is about to welcome India’s first underwater metro train, which will allow commuters to travel across the Hooghly River, which separates West Bengal’s capital from Howrah. On April 12, 2023, metro authorities conducted a trial run from Howrah Maidan to Esplanade, with only officials and engineers on board.
The authorities have built a tunnel under the Hooghly River with an internal diameter of 5.55 metres and external diameters of 6.1 metres. Tunnel-boring machines (TBMs) are used to complete tunnel construction. Prerna and Rachna, two German-made TBMs, completed the job in a record 66 days.
According to The Indian Express, authorities implemented several measures to prevent water inflow and leaks in the tunnel. To reduce water permeability, concrete mixes containing fly ash and micro-silica are used.
The task was especially difficult because the areas surrounding the underwater tunnelling site contained many historic buildings, and the authorities had to ensure that the buildings were not damaged as a result of the process.
